Question

How does water move in and out of the cells?

Answer 1

Water moves in and out of the cell:

1. Osmosis is the process by which solvent particles flow from a dilute solution to one that is more concentrated.
2. Diffusion, in contrast, is the movement of particles from a location of higher concentration to one of lower concentration.
3. Water moves by osmosis, which is a type of diffusion, into and out of the cell.
4. Through the cell membrane, water molecules flow through osmosis from a lower solute concentration to a higher solute concentration.
5. Water can therefore travel because of a concentration gradient without using any energy.
